Brad Marchand scored the decisive goal in the sixth round while Tuukka Rask stopped 5-of-6 shots in the shootout as the Bruins beat the Devils, 2-1 in overtime Tuesday night at TD Garden. The Bruins (5-0-1) have gained at least a point in all six games this season. The highlight of the shootout came when Tyler Seguin had to re-do his first shot that produced a goal because a fan threw something on the ice. Seguin repeated his effort and scored again.

The Bruins and Devils are the only teams in the Eastern Conference without a regulation loss so far, joining San Jose and Chicago in the West, who were perfect coming into Tuesday’s action.

The two teams battled to a scoreless tie in the opening 20 minutes. Each team recorded nine shots on goal but neither team sustained serious pressure. The main highlight of the first period was a fight between Boston enforcer Shawn Thornton and New Jersey tough guy Krys Barch. In a bout that lasted for nearly a minute and a half, Thornton landed several clean shots before the two were broken apart by the officials, with both teams applauding their skater for staying on their feet the entire time.

The Bruins killed off an Andrew Ference tripping penalty with five minutes left in the first, giving them 24 straight kills to open the season.

But the Bruins were not as lucky in the second period as Johnny Boychuk was whistled for tripping at 7:22. David Clarkson redirected a Marek Zidlicky shot from the left point past Tuukka Rask for the first power play goal allowed by the Bruins in 25 chances this season.

The Bruins would kill off the next three power play chances and finished the game 4-for-5 on the penalty kill. They are 27-of-28 on the penalty kill this season.

The Bruins came out with much greater intensity in the opening minute of the third period and were buzzing around Johan Hedberg. Boston’s best chance came when Dougie Hamilton fired a shot from the left point that just went wide, missing the stick of David Krejci. Instead of a goal, Krejci was called for goaltender interference, taking some momentum away from the Bruins.

With 8:15 left, the Bruins got another golden opportunity to tie the game when Dainius Zubrus was called for holding. Midway through the man advantage, Patrice Bergeron and Nathan Horton had point-blank chances only to be denied by Hedberg. Bergeron raced down the slot but was stopped and Horton couldn’t get the rebound past the Devils goalie on a clean look. Those would be the only two shots the Bruins managed on the power play.

The Bruins finished 0-for-3 on the power play and now stand 3-for-24 on the power play this season. But the Bruins would get the equalizer with 4:05 left in regulation when Horton finally beat Hedberg five-hole on a shot from the slot, his third of the season. Hedberg stopped all 25 Boston shots before the game-tying goal. Just 50 seconds into overtime, Krejci just missed on a backhander in front of Hedberg while Bergeron had a clean look on shot coming down the right wing moments later. Rask stopped Henrik Tallinder with just over two minutes left in overtime. Tyler Seguin had a chance to win it but his shot from the right wing missed the net short side.

The Bruins are off Wednesday before taking on the Sabres Thursday night at TD Garden. For complete coverage from the Garden from DJ Bean and Mike Petraglia, visit the Bruins team page at weei.com/bruins.
